CHAPTER 4 - OPERATION
OVERVIEW
Chapter 4 contains general and detailed instructions on how to operate the facility. Section I covers general subjects
including fuel quality control, measurement, and record keeping.
More emphasis on safety in operations is included. Section II gives basic operation instructions for the major equipment.
Section III covers commissioning and specific fuel movement and storage operations. Section IV covers some of the
special problems that may be encountered under adverse and unusual weather and site conditions. On Government
furnished equipment for which a specific technical manual has been published by the U.S. Army or by the manufacturer,
this manual will cover only the most important points of operation and will refer the reader to the specific technical
manual for further detail. It is beyond the scope of this manual to recommend or specify the numbers and qualifications
of operating personnel.
SECTION I - GENERAL
4-1 General Information
The TPT is designed to receive, store, and dispense any of three types of fuel; diesel, jet fuel, or motor gasoline. Fuels
are received from an associated pipeline system or from tanker trucks, or both, depending on specific site operating
criteria. Fuels can be dispensed to transport vehicles or directly to user vehicles. When the mission of the particular
terminal calls for it, fuels can be discharged from storage to an associated pipeline. For a thorough understanding of the
physical features of the TPT, it is necessary that the reader refer to the Chapter 2, Design, Equipment and System Data.
For applicable supporting information and U.S. Army practice the reader is referred to the Department of the Army
manuals listed in Appendix D.
4-1.1 Flow Diagram (P&ID)
For the convenience of the reader, the same P&ID as included in Chapter 2 has been altered to show normal flow
directions and is included in this chapter as Fig. 4-1. It is important that the reader fully understand the flow diagram
(P&ID with flow arrows). It should be noted that the P&ID flow diagram is strictly schematic and does not indicate relative
line and hoseline length nor does it necessarily represent the types of fittings at line junctions. The switching manifold,
for example, shows up schematically as quite long whereas in actual practice it is recommended that it be kept as short
as possible. Referring to Fig. 4-1, it is noted that fuel from the associated pipeline systems enters the switching manifold
near the left hand side of the diagram. The fuel, if contaminated with the previously received fuel of a different
specification (interface), or if otherwise contaminated, can be diverted to the contaminated fuel module. When sampling
assures the operators of clean specification fuel, the appropriate valves are opened to route the fuel to the tank farm
module desired and the valves to contaminated fuel module are closed. When called for by the specific operation at the
TPT site, fuel can also be received from the tanker-truck receipt manifold shown near the right-hand side of the diagram.
Incoming fuel quantities are measured by the meters in the intake hoselines to the fuel units. By proper positioning of
valves, the fuel can be routed to any module. Normally, fuel is received into the secondary modules for storage and then
transferred to the primary module for dispensing. Fuel can be transferred between modules with the hoseline pumps.
Fuel is sent to the dispensing assembly via the primary module hoseline pump(s) through filter separators to remove
traces of water. The fuel can be
